Spectral geometry of the Steklov problem
Abstract: The Steklov
problem is an eigenvalue problem with the spectral parameter in the
boundary conditions, which has various applications. Recently, there
has been a growing interest in the Steklov problem from the viewpoint
of spectral geometry. While this problem shares some common properties
with its more familiar Dirichlet and Neumann cousins, its eigenvalues
and eigenfunctions have a number of distinctive geometric features,
which makes the subject especially appealing. In the talk, based on a
joint survey paper with A. Girouard, we discuss some recent advances
and open questions, particularly in the study of spectral asymptotics,
spectral invariants, eigenvalue estimates, and nodal geometry.
